[0024] A vehicle lamp comprises the dual light module described in any one of the above embodiments.
[0025] Compared with the related art, the beneficial effects of the technical solution of this application are:
[0026] The dual-light module includes: a high-beam module, a low-beam module, an outer lens and a metal separator. The outer lens includes a high-beam area and a low-beam area, the high-beam area includes a first high-beam area and a second high-beam area, the high-beam module includes a first high-beam module and a second high-beam module, the first high-beam module includes a first light source and a first optical unit, the second high-beam module includes a second light source and a second optical unit, the low-beam module includes a third light source and a third optical unit, the metal separator includes a first separator and a second separator, the high-beam module and the low-beam module are respectively located on both sides of the first separator, the high-beam area and the low-beam area are also respectively located on both sides of the first separator, the second separator is located on the first separator, the first high-beam module and the second high-beam area module are respectively located on both sides of the second separator, the first high-beam area and the second high-beam area are also respectively located on both sides of the first separator.

At the same time, it is beneficial to the dispersed arrangement of the light source of the high beam module, and then it is beneficial to the heat dissipation of the high beam module. In addition, the dual-light module uses a metal separator instead of a plastic separator, which reduces the difficulty of preparing the separator and simplifies the structure of the separator, which is beneficial to the transmission of light in the module.

[0042] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the embodiments in the present application. Obviously, the described embodiments are only embodiments of one area of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.
[0043] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0044] As described in the background technology section, in the existing integrated high and low beam dual-light module, there will be an obvious dark line at the combination of the high beam and the low beam, which affects the lighting area and road lighting perception, and the lighting effect is poor.
[0045] Based on the above, the present application provides a dual-light module, such as Figure 1 As shown, the dual-light module includes: a high-light module 100 , a low-light module 200 , an outer lens 300 and a metal separator 400 .
[0046] like Figure 2 As shown, the outer lens 300 includes a high beam area 310 and a low beam area 320 arranged along a first direction, and the high beam area 310 includes a first high beam area 311 and a second high beam area 312 arranged along a second direction. The first direction and the second direction are both parallel to the mounting surface of the outer lens 300, and the first direction and the second direction are perpendicular to each other.
[0047] like Figure 3 As shown, the high beam module 100 includes a first high beam module 110 and a second high beam module 120 arranged along a first direction, the first high beam module 110 includes a first light source 111 and a first optical unit 112, and the second high beam module 120 includes a second light source 121 and a second optical unit 122. Specifically, in response to the high beam control instruction, the high beam module 100 controls at least a portion of the light-emitting surface of the first light source 111 to emit a first high beam, and controls at least a portion of the light-emitting surface of the second light source 121 to emit a second high beam, the first high beam region 311 of the outer lens 300 is located on the transmission path of the first high beam, and the second high beam region 312 of the outer lens 300 is located on the transmission path of the second high beam, so that the first high beam can be projected through the first high beam region 311, and the second high beam can be projected through the second high beam region 312, and then the first high beam and the second high beam are superimposed to form a high beam light pattern. It should be noted that, in one embodiment of the present application, the first light source 111 includes a plurality of LEDs, and the second light source 121 includes a plurality of LEDs, wherein the light beam emitted by each LED constitutes a pixel of the high beam light type. Figure 4 Specifically, in response to the high beam control instruction, at least part of the LEDs in the first light source 111 are turned on, and at least part of the LEDs in the second light source 121 are turned on, and then at least part of the light emitting surface of the first light source 111 emits a first high beam, and at least part of the light emitting surface of the second light source 121 emits a second high beam, that is, the high beam pattern formed by the superposition of the first high beam and the second high beam can be controlled, as shown in FIG. Figure 5 As shown, the purpose of adaptive anti-glare can be achieved.
[0048] like Figure 6 As shown, the low beam module 200 includes a third light source 210 and a third optical unit 220. The low beam module 200 responds to the low beam control instruction to control the third light source 210 to output a low beam. The low beam area 320 of the outer lens 300 is located on the transmission path of the low beam and receives the low beam, so that the low beam can be projected through the low beam area 320 to form a low beam light pattern, such as Figure 7 As shown, Figure 7 This is a schematic diagram of the superimposed light pattern of high and low beams.
[0049] The metal separator 400 includes a first separator 401 and a second separator 402. The high beam module 100 and the low beam module 200 are respectively located on both sides of the first separator 401. The high beam area 310 is opposite to the high beam module 100, and the low beam area 320 is opposite to the low beam module 200. The high beam area 310 and the low beam area 320 are also respectively located on both sides of the first separator 401. The second separator 402 is located on the first separator 401 and is located on the same side of the first separator 401 as the high beam module 100. Specifically, the first high beam module 110 and the second high beam area module 120 are respectively located on both sides of the second separator 402. The first high beam area 311 is opposite to the first high beam module 110, and the second high beam area 312 is opposite to the second high beam module 120. The first high beam area 311 and the second high beam area 312 are also respectively located on both sides of the first separator 401.
[0050] As can be seen from the above, the high beam module 100 and the low beam module 200 of the dual light module are independent of each other, so that the high beam and the low beam will not interfere with each other, and both can form a complete low beam light type and a high beam light type. Since the high beam module 100 and the low beam module 200 share the same outer lens 300 and are projected through different areas of the outer lens 300, the dark seam problem when the high beam light type and the low beam light type are superimposed can be effectively suppressed, so that there is no obvious dark seam when the high beam light type and the low beam light type are superimposed, thereby improving the lighting effect. At the same time, the high beam module 100 includes a first high beam module 110 and a second high beam module 120, and the high beam light type is composed of the first high beam and the second high beam, which can improve the high beam light effect, and help to achieve the light type adjustment of the high beam light type, and improve the high beam lighting effect. In addition, it is also beneficial to the dispersed arrangement of the high beam module light source, and then to the heat dissipation of the high beam module, so that the heat dissipation fan of the high beam module can be cancelled when the heat dissipation requirements are met, thereby reducing costs and carbon emissions.
[0051] In addition, the high beam module 100 and the low beam module 200 of the dual-light module are separated by a metal separator, the first high beam module 110 and the second high beam module 120 of the high beam module 100 are also separated by a metal separator, and the first high beam area 311, the second high beam area 312 and the low beam area 320 of the outer lens 300 are also separated by a metal separator. In other words, the dual-light module can separate the functional areas using a single metal separator. Compared with the related art, while achieving the function of shielding stray light, it avoids using a separator composed of multiple plastic parts to separate the functional areas, reduces the difficulty of preparing the separator, and simplifies the structure of the separator, which is beneficial to the transmission of light in the module. It should also be noted that when the separator is a metal separator, due to the hardness and ductility of the metal, the thickness of the metal separator, i.e., the metal separator 400, can be 0.1 mm, while the thickness of the plastic separator is as high as 2 mm to 3 mm. At the same time, the plastic separator also has a draft angle, which will cause the plastic separator to be larger in size and occupy more module space, which is not conducive to light transmission and module miniaturization.
[0052] Based on the above embodiments, in one embodiment of the present application, the first high beam is projected through the first high beam area 311 to form a high beam pattern, the second high beam is projected through the second high beam area 312, and the second high beam overlaps with the middle area of the first high beam, that is, the second high beam is projected into the middle area of the first high beam, such as Figure 8 As shown, it can be used to increase the central brightness of the high beam pattern.
[0053] In another embodiment of the present application, the first high beam is projected through the first high beam area 311 to form a high beam pattern, and the second high beam is projected through the second high beam area 312. The second high beam at least partially does not overlap with the first high beam, that is, after being projected through the second high beam area 312 of the outer lens 300, the second high beam partially overlaps with the first high beam, or does not overlap with the first high beam at all. That is, the second high beam and the first high beam can be arranged in an alternating manner, for example. Fig. 9 and Fig.10 As shown, the second high beam and the first high beam are arranged alternately up and down. It should be noted that Fig. 9 and Fig.10 It is only a schematic diagram that the second high beam and the first high beam at least partially do not overlap. In other embodiments of the present application, the staggered arrangement of the first high beam and the second high beam may be other arrangements, which is not limited in the present application and depends on the specific circumstances.
[0054] Based on the above, the first high beam module 110 is used to form a high beam light pattern, which can be specifically the overall width of the high beam light pattern and the upper widening of the high beam light pattern. The second high beam module 120 is an auxiliary module of the high beam light pattern, which is used to increase the intermediate brightness of the high beam light pattern, or to diffuse the range of the high beam light pattern, that is, to increase the pixel partition of the high beam light pattern to improve the high beam lighting effect.
[0055] Based on the foregoing embodiments, in one embodiment of the present application, Figure 2 As shown, for the outer lens 300, the light incident surface of the first high beam area 311 thereof has a micro-pattern structure, that is, the surface of the first high beam area 311 facing the first high beam module 110 is designed with a micro-pattern structure, which is used to improve the uniformity of the first high beam projected by the first high beam area 311, suppress the dark area problem in the high beam illumination area, and further improve the dark seam problem when the high beam light type and the low beam light type are superimposed. It should be noted that the above-mentioned micro-pattern structure can be vertical stripes, rectangular patterns, etc., which is not limited in this application and depends on the specific situation.
[0056] Based on the foregoing embodiments, in one embodiment of the present application, Figure 3 As shown, the first optical unit 112 includes at least one first inner lens 1121 arranged along the first direction. Specifically, the first inner lens 1121 has a first light incident surface 11211, a first reflection surface 11212, a second reflection surface 11213 and a first light emitting surface 11214. The first light incident surface 11211 is opposite to the light emitting surface of the first light source 111. The first high beam enters the first inner lens 1121 through the first light incident surface 11211, and then is totally reflected by the first reflection surface 11212 and the second reflection surface 11213 in sequence, and is emitted from the first light emitting surface 11214 to the first high beam area 311.
[0057] The second optical unit 122 includes at least one second inner lens 1221 arranged along the first direction, the second inner lens 1221 has a second light incident surface 12211, a third reflection surface 12212, a fourth reflection surface 12213 and a second light emitting surface 12214, the second light incident surface 12211 is opposite to the light emitting surface of the second light source 121, the second high beam enters the second inner lens 1221 through the second light incident surface 12211, and then is totally reflected by the third reflection surface 12212 and the fourth reflection surface 12213 in sequence, and is emitted from the second light emitting surface 12214 to the second high beam area 312. Based on the above, through the reflection of the first high beam unit 112 and the second high beam unit 122, the optical path of the high beam can be effectively folded, thereby shortening the length of the high beam module, which is conducive to the miniaturization trend of the vehicle light module.
[0058] Among them, the focus of the first high beam area 311 is located on the second reflection surface 11213, so that the first high beam light beam is transmitted to the first high beam area 311 as much as possible, and the focus of the second high beam area 312 is located on the fourth total reflection surface 12213, so that the second high beam light beam is transmitted to the second high beam area 312 as much as possible, thereby helping to improve the light efficiency of the dual light module.
[0059] Based on the aforementioned embodiments, in one embodiment of the present application, the shapes of the first inner lens 1121 in the at least one first inner lens 1121 are the same, and the shapes of the second inner lens 1221 in the at least one second inner lens 1221 are the same, that is, the shapes of the first inner lens 1121 in the first optical unit 112 are the same, and the shapes of the second inner lens 1221 in the second optical unit 122 are the same, which can be used to realize the basic high beam function.
[0060] In another embodiment of the present application, at least some of the first inner lenses 1121 in the at least one first inner lens 1121 have different shapes, and at least some of the second inner lenses 1221 in the at least one second inner lens 1221 have different shapes, that is, at least some of the first inner lenses 1121 in the first optical unit 112 have different shapes, and at least some of the second inner lenses 1221 in the second optical unit 122 have different shapes. Since the light beam passes through lenses of different shapes, its light type will also change, so the first optical unit 112 and the second optical unit 122 can adjust the high beam light type, and thus can also achieve different high beam functions, such as high beam auxiliary lighting. That is to say, the first high beam unit 112 and the second optical unit 122 can design and combine the shapes of the first inner lens 1121 and the second inner lens 1221 according to the requirements of the high beam function, and design different high beam light types, such as Fig.11 As shown, different high beam functions can be realized, and personalized design can also be achieved based on user needs.
[0061] Based on the foregoing embodiments, in one embodiment of the present application, Fig.12 As shown, the third optical unit 220 includes at least one third inner lens 221 arranged along the first direction. The third inner lens 221 is located at the focus of the low beam area 320, and the focal length of the low beam area 320 is less than the preset focal length, that is, the focal length of the low beam area 320 can be smaller, thereby reducing the height of the low beam area 320. Specifically, the height of the outer lens 300 can be less than 30 mm, wherein the height of the low beam area 320 can reach 10 mm, or even less.
[0062] The third inner lens 221 has a third light incident surface 2211, a fifth reflection surface 2212, a sixth reflection surface 2213 and a third light emitting surface 2214. The low beam enters the third lens 221 through the third light incident surface 2211, and is emitted from the third light emitting surface 2214 to the low beam area 320 through the fifth reflection surface 2212 and the sixth reflection surface 2213 in sequence. The reflection of the third inner lens 221 can effectively fold the transmission path of the low beam, reduce the length of the low beam module, and contribute to the miniaturization trend of the vehicle light module. Among them, the area of the fifth total reflection surface 2212 close to the third light incident surface 2211 has a cutoff line structure for forming a cutoff line of the low beam light type, that is, the dual light module cancels the existing cutoff line light type baffle, and uses the third inner lens 221 to form a cutoff line, avoiding the light type baffle blocking the light transmission, which helps to improve the light efficiency, and can also effectively ensure the superposition effect of the high and low beams, and suppress the dark seam problem.
[0063] In addition, the third light emitting surface 2214 is located between the fifth emitting surface 2212 and the sixth reflecting surface 2213, and the fifth reflecting surface 2212 is not connected to the third light emitting surface 2214, and the distance between the side of the fifth reflecting surface 2212 close to the third light emitting surface 2214 and the sixth light emitting surface 2213 in the third direction is a first distance, and the first distance is less than the length of the third light emitting surface 2214 along the third direction, and the third direction is parallel to the arrangement direction of the fifth light emitting surface 2212 and the sixth light emitting surface 2213, that is, the fifth reflecting surface 2212 and the sixth reflecting surface 2213 form a light exit port whose size is smaller than the size of the third light emitting surface 2214, that is, an aperture whose size is smaller than the size of the third light emitting surface 2214 is formed between the fifth reflecting surface 2212 and the sixth reflecting surface 2213, which can compress the low beam and emit it from the low beam area 320, which helps to reduce the height of the low beam area 320, and then reduce the height of the outer lens 300.
[0064] Based on the aforementioned embodiments, in one embodiment of the present application, the structure of the third inner lens 221 in the at least one third inner lens 221 is the same, that is, the structure of the third inner lens 221 in the optical unit of the low beam module 200, namely the third optical unit 220, is the same, and the basic low beam function can be realized.
[0065] In another embodiment of the present application, the structures of at least some of the at least one third inner lens 221 are different, that is, the structures of at least some of the third inner lenses 221 in the optical unit of the low beam module 200, that is, the third optical unit 220, are different. The shapes of the third inner lenses 221 can be designed and combined according to the requirements of the low beam function, such as the adaptive low beam lighting function, or the personalized design requirements of the customer, so as to obtain a low beam light type that meets the design requirements, such as Figure 13-Figure 15As shown, the low beam light type obtained by combining different third inner lenses 221 is more practical.
[0066] It should be noted that the shape design of the first inner lens 1121, the second inner lens 1221 and the third inner lens 221 can be achieved by surface cutting, optical surface removal, optical surface addition, etc., and the present application does not limit this, and it depends on the specific situation.
[0067] It should also be noted that the first inner lens 1121, the second inner lens 1221 and the third inner lens 221 can be TIR reflectors, which can realize the output of high and low beam light types through total reflection, and have higher light efficiency. However, in other embodiments, the third inner lens 221 can also be a concentrator, etc., depending on the specific situation.
[0068] Based on the above embodiments, in one embodiment of the present application, the first high beam area 311 of the outer lens 300 is a focus discrete lens, and the second high beam area 312 is a focus discrete lens. Specifically, the first high beam area 311 and the second high beam area 312 are single focus lenses, but the focus of the first high beam area 311 and the second high beam area 312 is made into a small range of focus discrete, in order to improve the uniformity of the first high beam light beam and the second high beam light beam and suppress dispersion.
[0069] The low beam area 320 of the outer lens 300 is a focal line lens, that is, the outer lens 300 is composed of two focal lenses and one focal line lens, which can effectively reduce the thickness of the outer lens 300. Specifically, the thickness of the outer lens can be less than 500 mm, thereby reducing the weight and cost of the outer lens 300.
[0070] Based on the foregoing embodiments, in one embodiment of the present application, the first light source 111 includes a first PCB board 1111 and a first LED 1112 located on the first PCB board 1111, the second light source 121 includes a second PCB board 1211 and a second LED 1212 located on the second PCB board 1211, and the third light source 310 includes a third PCB board 321 and a third LED 322 located on the third PCB board 321.
[0071] Among them, Figure 6 As shown, the light emitting direction of the first LED 1112 is parallel to the arrangement direction of the high beam module 100 and the outer lens 300, the light emitting direction of the second LED 1212 is parallel to the arrangement direction of the high beam module 110 and the outer lens 300, and the light emitting direction of the third LED 322 is parallel to the arrangement direction of the low beam module 200 and the outer lens 300.
[0072] Since the LED is placed on the PCB board, the light-emitting direction of the LED will be perpendicular to the plane where the PCB board is located, and due to the total reflection of the low beam and the high beam, if the arrangement direction of the high and low beam modules and the outer lens in the module is regarded as the horizontal direction, the first PCB board, the second PCB board and the third PCB board can be placed vertically in the module. Such a layout module has a good thermal cycle, is conducive to the heat dissipation of the light source, and is easy to install. It should be noted that in other embodiments of the present application, the first PCB board, the second PCB board and the third PCB board can also be placed tilted in the module, such as Fig.16 shown.
[0073] Based on the above, the dual-light module provided in the present application can effectively improve the optical efficiency by more than 50% through the structural improvements of the high-beam module 100, the low-beam module 200 and the outer lens 300.
[0074] Correspondingly, the present application also provides a vehicle lamp, which includes the dual-light module described in any of the above embodiments.
[0075] In summary, the present application provides a dual-beam module and a headlight, the dual-beam module comprising: a high-beam module, a low-beam module, an outer lens and a metal separator. The outer lens comprises a high-beam area and a low-beam area, the high-beam area comprises a first high-beam area and a second high-beam area, the high-beam module comprises a first high-beam module and a second high-beam module, the first high-beam module comprises a first light source and a first optical unit, the second high-beam module comprises a second light source and a second optical unit, the low-beam module comprises a third light source and a third optical unit, the metal separator comprises a first separator and a second separator, the high-beam module and the low-beam module are respectively located on both sides of the first separator, the high-beam area and the low-beam area are also respectively located on both sides of the first separator, the second separator is located on the first separator, the first high-beam module and the second high-beam area module are respectively located on both sides of the second separator, the first high-beam area and the second high-beam area are also respectively located on both sides of the first separator. The low-beam module responds to the low-beam control instruction to control the third light source to output a low-beam beam, and the low-beam beam is projected through the low-beam area to form a low-beam light pattern. The high beam module responds to the high beam control instruction, controls at least part of the light-emitting surface of the first light source to emit a first high beam, and controls at least part of the light-emitting surface of the second light source to emit a second high beam. The first high beam is projected through the first high beam area, and the second high beam is projected through the second high beam area, and they are superimposed to form a high beam light pattern.
[0076] From the above, it can be seen that the high beam module and the low beam module of the dual-light module are independent of each other, so the high beam and the low beam will not interfere with each other, and both can form a complete low beam light type and high beam light type. Because the high beam module and the low beam module share the same outer lens and are projected through different areas of the outer lens, the dark seam problem when the high beam light type and the low beam light type are superimposed can be effectively suppressed, so that there is no obvious dark seam when the high beam light type and the low beam light type are superimposed, thereby improving the lighting effect. At the same time, the high beam light type is composed of the first high beam light beam and the second high beam light beam, which can improve the high beam light effect and improve the high beam lighting effect. At the same time, it is beneficial to the dispersed arrangement of the light source of the high beam module, and then it is beneficial to the heat dissipation of the high beam module. In addition, the dual-light module uses a metal separator instead of a plastic separator, which reduces the difficulty of preparing the separator and simplifies the structure of the separator, which is beneficial to the transmission of light in the module.
